What is a Sheet-Like Layer of Cells with No Extracellular

Question

What is a sheet-like layer of cells with no extracellular matrix in between?  
A) Connective tissue
B) Adhering junction
C) Tight junction
D) Basement membrane
E) Epithelial tissue

Accepted Answer

Epithelial tissue is a sheet-like layer of cells that is tightly packed with no extracellular matrix in between. Connective tissue has extracellular matrix and is not sheet-like. Adhering junctions and tight junctions are specialized cell junctions found between cells, but do not form a layer of cells. Basement membranes are thin, sheet-like layers of extracellular matrix that are found beneath epithelial tissues.
